I had Hosmer at the start of the year then went to LaRoche for awhile but am now picking Hosmer back up. If I make this trade I can put Andrus in to play SS. Tulo has been great though so far. Would love to hear what you guys/gals think. Thanks.

I really don't think this trade would be beneficial to you. If you've never owned Tulowitzki before, you may not be aware that he hits at a torrid pace in the second half, to the tune of .321 with 68 homers as opposed to .267 with 62 homers in the first half (and keep in mind the second half is shorter than the first). The best is easily yet to come for Tulowitzki.

I do think getting Fielder would be good for your team though. Try to sell high on Viciedo (who, during his hot streak, has been striking out at an astronomical rate) and package him with Hosmer. Or perhaps try to get the Fielder owner to bite on Andrus, who has had a very hot start but will not finish the season better than Tulo, IMO. And if that doesn't work, I would just put Andrus in at your Util position over Prado and call it good for now. Hosmer will come around eventually, he's just really far in the doldrums right now. No way he stays down like this for a year.
